Advancing Hepatitis C Elimination through Opt-Out Universal Screening and Treatment in Carceral Settings, United States

Incarcerated persons are infected with hepatitis C virus (HCV) at rates ≈10 times higher than that of the general population in the United States. To achieve national hepatitis C elimination goals, the diagnosis and treatment of hepatitis C in incarcerated persons must be prioritized. In 2022, the Centers for Disease Control and Prevention recommended that all persons receive opt-out HCV screening upon entry into a carceral setting. We review recommendations, treatments, and policy strategies used to promote HCV opt-out universal HCV screening and treatment in incarcerated populations in the United States. Treatment of hepatitis C in carceral settings has increased but varies by jurisdiction and is not sufficient to achieve HCV elimination. Strengthening universal HCV screening and treatment of HCV-infected incarcerated persons is necessary for HCV elimination nationwide.

We review policy strategies to implement HCV opt-out universal screening and treatment in incarcerated populations.Strengthening HCV elimination policies and practices in carceral settings is critical to achieving national HCV elimination.

Hepatitis C Screening Evolution and Current Recommendations
Guidelines for testing and screening for HCV in the United States have evolved since the original recommendations were first published by the Centers for Disease Control and Prevention (CDC) in 1991 (Fig- ure).Although risk-based HCV testing was recommended in 2003, it missed a substantial proportion of persons with HCV (19).During 2019-2020, the American Association for the Study of Liver Diseases (AASLD), Infectious Diseases Society of America (IDSA), US Preventive Services Task Force, and CDC recommended universal HCV screening for all adults at least once during a lifetime (15,20,21).CDC (2022) and AASLD/IDSA (2023) recommended universal opt-out HCV intake screening of incarcerated and detained persons (22,23).
Models estimate that universal opt-out screening in US prisons would diagnose >122,000 HCV infections and prevent ≈13,000 new prison-associated infections, ≈2-3 times more than would be possible with risk-factor based assessments (24).Implementing universal opt-out HCV screening and associated treatment costs would increase state prison healthcare budgets by an estimated 12.4% (24).Thus, budgetary constraints might limit the broader adoption of universal opt-out HCV screening and treatment.
Partnerships between carceral facilities and departments of health are promising strategies to enact universal opt-out HCV testing.The Indiana Department of Health embedded an epidemiologist in the Indiana DOC and began universal HCV screening at intake, which ultimately identified a 12% intake viremia prevalence (26).The collaboration between Indiana's Department of Health and DOC resulted in a transition to universal treatment, the creation of a Hepatitis C Elimination in Carceral Settings peer education program, a community care transition program, and development of data tracking capabilities to generate HCV care cascades (26).

Hepatitis C Treatment Evolution and Current Recommendations
During 1998-2014, interferon-based therapies were the gold standard for hepatitis C treatment but were ineffective, poorly tolerated, and unsafe for many persons (27).The approval of sofosbuvir in 2013 shifted the treatment paradigm toward safe, highly efficacious, oral DAA therapies that had >95% sustained virologic response (SVR) rates and few contraindications (15,28).SVR is defined as no detectable HCV RNA in blood after completing treatment.Attaining SVR after treatment with DAAs reduced all-cause mortality, end-stage liver disease, and hepatocellular carcinoma among Medicare beneficiaries during 2014-2016 (14).In 2019, the AASLD/IDSA recommended treating all patients with current HCV infection except those who had a short life expectancy that cannot be remediated by HCV therapy (15).Although treatment remains expensive, manufacturer competition and negotiated pricing have substantially driven down DAA costs.
Considerable costs associated with chronic liver disease can be prevented by treating HCV infection.
In 2019, the estimated annual cost of sequelae from chronic HCV infections ranged from $17,500 per year for nonadvanced fibrosis to $262,000 within the year after a liver transplant (29).Cost-benefit analyses show that universal opt-out screening in prisons is cost-effective, reducing ongoing HCV transmission, the incidence of advanced liver diseases, and death from liver disease (24).A 2020 study found that a test all, treat all, and linkage to care at release model would cost prisons $1,440 per person and result in a 23% increase in lifetime SVR and 54% reduction of cirrhosis cases (30).

HCV Treatment in Carceral Settings-Real-World Examples
Financial and other barriers continue to limit access to HCV treatment in US carceral settings (Table 2).However, some initiatives have demonstrated promising outcomes.

Innovative Payment Models
Despite recent cost reductions, DAA treatment remains expensive; an average wholesale price is $26,000-$90,000 per treatment course (31).Innovative payment models were launched by Louisiana and Washington in 2019 to reduce the cost of Although increased HCV treatment among Medicaid recipients has been shown in Washington and Louisiana, the effects of those innovative payment models on HCV treatment among incarcerated persons has not been reported (32).

Decentralized HCV Care
The Extension for Community Healthcare Outcomes model, first piloted in New Mexico in 2003, uses telehealth consultations between HCV experts and on-site correctional health professionals to train primary care providers to treat hepatitis C (33).The model program also established a peer education program that trains incarcerated persons to educate their peers about risk factors for HCV infection, the consequences of infection, and benefits of treatment and enables persons who previously refused testing or treatment the opportunity to reconsider.The New Mexico Corrections Department began universal screening in 2018 and had a hepatitis C prevalence of 40%-45% in their carceral population (34).In 2020, New Mexico allocated $22 million over 5 years for hepatitis C testing and treatment; >2,100 persons were treated during 2021-2023 (35,36).

Litigation and State Policy
Recent court rulings have shown that the threat of HCV-related litigation can expand access to treatment, expediting progress toward HCV elimination in carceral settings.Arguments primarily assert that denial of treatment violates the 8th Amendment of the US Constitution prohibiting cruel and unusual punishment (Table 3) (37,38).According to a seminal 1976 ruling in Estelle v. Gamble, carceral facilities must avoid deliberate indifference to patient health needs (39,40).Although AASLD/IDSA guidelines established universal hepatitis C treatment as a standard of care, carceral settings have used prioritization criteria to limit DAA treatment on the basis of liver fibrosis stage or other clinical manifestations.Courts have ruled differently on whether prioritization criteria used in some carceral settings constitute deliberate indifference (41).
A federal class action suit representing persons with HCV infection who were denied treatment during incarceration was filed against the Tennessee DOC (Atkins v. Parker, 2016).In response to the lawsuit, the Tennessee legislature provided the Tennessee DOC with new funding for hepatitis C treatment ($25 million by 2019), even though the DOC's prioritization policy was ultimately found to be lawful, and the ruling was affirmed on appeal (42).This investment increased the number of incarcerated persons receiving DAA treatment in the Tennessee DOC system from 1 in 2016 to 956 in 2021 (43).

Intersection of HCV Elimination and Substance Use Treatment
Proponents of expanded DAA treatment to prevent chronic HCV infection in incarcerated persons must also contend with substance use disorder and the overdose crisis among persons who inject drugs (PWID).Although robust evidence exists indicating that providing sterile injecting equipment reduces HCV transmission, no carceral facility currently provides sterile injection equipment.Persons released from prisons or jails are 10-40 times more likely to die from an overdose than are persons in the general population; the greatest risk for death is 3-4 weeks after release (44,45).Medications for opioid use disorder (MOUD), such as methadone, naltrexone, and buprenorphine, are highly safe and efficacious.Exposure to MOUD during incarceration is associated with 85% reduction in all-cause mortality and 75% reduction in overdose-related deaths in persons after reentry into the community (45).
MOUD is a critical component of HCV prevention because it decreases unsafe injecting practices in PWID; MOUD alone can reduce the risk for HCV infection by 50% and reinfection by 73% among PWID (46).Initiating HCV treatment also increases the uptake of MOUD (47).As of 2022, a total of 15 laws across 12 US states had expanded access to MOUD in prisons and jails for substance use treatment (45).

Linkage to Care
Lack of insurance coverage and lack of coordinated handoff between carceral and community healthcare systems complicate healthcare transitions for incarcerated persons after release (48).California was the first state to apply for Section 1115 waivers of the Medicaid Inmate Exclusion Policy to secure payment coverage for substance use treatment for persons who would otherwise lose coverage during incarceration under that Medicaid policy (49).Although DAAs are included, waivers are unlikely to directly increase DAA treatment because many persons are treated during incarceration.However, the waivers can substantially improve linkage to care for MOUD and mental health treatment to prevent new or recurrent HCV infection after release.

Future Directions
National data on the incidence and prevalence of HCV in carceral settings is required to improve HCV surveillance efforts and monitor progress across the country.Collaboration between US public health organizations and DOCs is essential both for data collection and improved control of HCV transmission in the carceral setting.Identifying facility-specific barriers and allocating data-driven resources are critical to improve HCV surveillance and treatment.
The US Congress is currently considering funding for a National Hepatitis C Elimination Initiative.This $11.3 billion initiative would enhance screening, testing, treatment, prevention, and monitoring of hepatitis C for all Americans; the goal is to reach elimination targets within a 5-year period (50).Of note for incarcerated persons, the plan includes point-of-care HCV RNA testing, provider training and technical assistance for implementation, and a national drug procurement plan that would cover incarcerated or detained persons.Carceral facilities can make considerable steps toward elimination now by using
